    Abstract

    An implicit boundary condition procedure is employed in the.solution of one-dimensional Euler equations by the implicit finite dixA3;erence scheme of Beam and warming. The implicit boundary point trecitment is-based on the method of characteristics. Implementation of the procedure is illustrated using the subsonic inflow and outflow conditions for a quasi-one-dimensional Laval nozzle flow. Results show that implicit application of boundary conditions. enhances the potential of the implicit algori thrn by permitting the use of large time steps.
